Abstract: A method for providing a flexible method for applying computationally significant association information in graphical input systems to information data using unrecognized visual information is disclosed. A method is provided to mark and index user-produced information with special information designators called key objects which can later be used as access mechanisms into the user-produced notes, without recognition of the notes. Visually recognizable, but computationally unrecognized, image segments are designated key objects. A key object is assigned a unique identifier that is computationally distinguishable from other key object identifiers. Key objects are associated with other data objects by attaching the key object identifier to other data objects in a data structure. A key object is easily created and reused, and provides a flexible and powerful indexing tool into graphically significant information without requiring the use of expensive or sophisticated recognition algorithms.

Inventor: KREMER WILHELM
IPC: H04L12/46
Filed: 1994-08-12
Abstract: The possibility of passing off apparent "good" higher level digital signals that may include corrupted or failed lower level digital signals because of inter-ring grooming of the lower level digital signals from a bidirectional line-switched ring to a path-switched ring and vice versa which employ first and second shared nodes is minimized by dual feeding communications circuits from the bidirectional line-switched ring to the path-switched ring and vice versa via the shared nodes. An inter-ring groomed communications circuit is provisioned from a secondary ring node in the line-switched ring of one of the shared nodes (secondary communications circuit) to be supplied to a primary ring node in the other of the shared nodes of the line-switched ring. A replica of the secondary communications circuit is demultiplexed to obtain the lower level digital signals, which are evaluated on a pair-wise basis with corresponding lower level digital signals from the primary ring node. The least corrupted of the evaluated lower level signals are selected to be combined into a new primary communications circuit which is to be inserted in the line-switched transmission path. An inter-ring groomed communications circuit is provisioned from a secondary ring node of one of the shared nodes in the path-switched ring to be supplied to a primary ring node in the other shared node of the path-switched ring. The secondary communications circuit is demultiplexed to obtain the lower level signals which are evaluated on a pair-wise basis with lower level signals from a corresponding primary communications circuit to determine which of the lower level signals are least corrupted. The selected least corrupted lower level signals are combined into a new primary communications circuit which is then dual fed in the path-switched ring primary ring node.

Patent CA-2133052-A1 (CA)
Inventor: QUICK JOHN
IPC: F24H9/12
Filed: 1994-09-27
Abstract: A direct vent gas baseboard heater has field installable concentric air intake tube and exhaust pipe. The intake pipe and exhaust tube can be cut separately from the remainder of the heater, improving the efficiency of installation. They can also be transported aligned with the remainder of the heater, reducing packaging size. The manufacturer can provide a single size of tube and pipe for a variety of installation situations. The tube connects to a base cabinet through a key hole configuration of tabs and cuts, and is twisted until the tabs meet stops in the base cabinet. An extrusion in an air box in the base cabinet is brought against a gasket on a flange of the tube, fixing the tube and sealing it with the air box. The exhaust tube has a threaded end and is threaded into an exhaust outlet in the air box, sealing it to a heat exchanger. A vent seal kit creates a seal assembly having a resiliently deformable ring seal extending into a wall sleeve with straps. The assembly is inserted ring first into a hole in a structure which deforms the seal by bending it back. When the seal emerges through the structure, it rebounds to its original position and the straps are pulled. This brings the seal into contact with the exterior wall, sealing it. Insulation is sprayed from the interior about the wall sleeve, sealing the internal cavity. An O-ring is slipped over the intake tube previously installed on the heater. The intake tube and exhaust pipe are inserted through the wall sleeve, sealed to the wall sleeve by the O-ring. The seal assembly allows the entire installation process to take place from the interior and is particularly advantageous for high-rise installations.

Title: Breakaway lever clutch with vertical lift trim
Inventor: MADER GERALD E
IPC: E05B17/00
Filed: 1994-12-19
Abstract: A door lever assembly for disengaging an unlocked latch of a lockable door latch assembly includes a lever handle rotatably connected to a trim housing supporting a stop plate.  A cam is operably connected to the lever handle and positioned to rotate in response to rotation of the lever handle, converting its rotational movement to linear movement of a movable slider positioned adjacent to the cam.  A lift arm is operably connected to vertical rods of the door latch assembly and an over-ride spring is connected between the slider and the lift arm.          The over-ride spring transmits motion of the slider to the lift arm to lift the lift arm and the connected vertical rods when the door latch assembly is in an unlocked position.  The over-ride spring compresses in response to slider movement when the blocking slide is positioned to block movement of the lift arm when the door latch assembly is in its locked position, preventing damage to components of the door lever assembly.  In an unlocked position, a pivot rotates to control contact between the slider and the stop plate.

Title: Fluid overfill protection and product identification system
Inventor: CADMAN GARY R
IPC: G01F23/292
Filed: 1995-08-03
Abstract: A fluid overfill and identification system uses a pulsed signal to both detect an overfill condition and identify a fluid product contained in a compartment. The pulsed signal is converted into an optical pulsed signal which is used with a retroreflective prism to detect when a fluid in the compartment has reached a desired capacity. Encoded in the pulse width of the same pulsed signal is the specific fluid product located in the compartment. Furthermore, different pulse frequencies are provided depending on whether the tanker truck is at a service station or at a loading terminal, thus allowing the system to distinguish between the two. At a marketing terminal, a new code is loaded into the system as a new fluid product is loaded into a compartment. A residue sensor may detect residual fluid in the compartment, and prevent the loading of a new fluid product and a new ID code.
